ELEVATING AND DUMPING APPARATUS.

Specification of Letters Patent.

Application filed January 8, 1912, Serial No. 670,100. Re ewed February 6, 1914. Serial No. 817,053."

ed certain new and useful Improvements in Elevating and Dumping Apparatus, of which the following is a specification.

This invention relates to elevating and dumping apparatus, and has for its object to produce an efficient and reliable means whereby loose material such as coal, earth, manure and the like, may be easily and cheaply raised and, loaded into wagons or carts, the invention being designed more especially as an improvement in the loader on which Patent Number 987,198 was issued to me March 21, 1911.

WVith this general object in View and others as hereinafter appear, the invention consists in certain novel and peculiar features of construction and organization as hereinafter described and claimed; and in order that it may be fully understood reference is to be had to the accompanying drawing in which I I b Figure 1, is a top plan view of an elevating and dumping apparatus embodying my invention, said figure showing the dumping I apparatus in dumping position and with an inclined approach, omitted. FigQQ, 1s a vertical section on the line 11-11 of .Fig. 1. Fig. 3, is a side elevation of the apparatus with what may be termed the descending bridge omitted and with the other parts in their initial positions. Fig. 4, is a cross section on theline IV-IV of Fig. 1. Fig.

5, is a fragmentary perspective view on an enlarged scale to show clearly the connection between the base andelevating members of the apparatus.

In the said drawings the base member'of the apparatus is constructed as follows: 1 and 2 indicate cross bars to rest upon the ground. 3 are parallel side bars upon and vided at their front ends with segmental recesses 4, and in their upper edges with recesses 5, and secured to the outer sides of said bars 3 in the vertical planes of recesses 5 are keepers 6. 7 is a cross bar connecting the opposite ends of side bars 3 from the recessed ends thereof, and secured centrally in said cross bar is a holder 8, containing a horizontally-arranged sheave 9 which projects beyond the outer side of bar 7, for a purpose which hereinafter appears. 10 are stringers secured to the inner sides of theiside bars 3, and provided at suitable points with anti-friction track rolls 11, which project slightly abovethe upper sides of the string- .ers 10, these stringers and rolls constituting a pair of trackways. .12 indicates a pair of bridges consistingof boards nailed or otherwise secured upon cross cleats 13. These bridges are arranged in inclined position with thelr lower ends resting uponv the ground and their upper ends resting upon the side bars 3. The upper ends of the cleats fit 1n notches 5, and to guard against accldental dislodgmentfof the bridges they are provided with depending hooks 1 1 for engagement with the underlying keepers 6, it being obviousthat the bridges can be readily placed in or removed from operative position.

Patented Dec. 15, 1914.

The .elevating member of the apparatus is constructed as follows: 15. indicates a pair of parallel side bars spaced apart to correspond to the'side bars 3 and rounded at their lower end to fit in the recesses 4 in the ends of said bars 3, and said bars are connected by a plurality of suitablyi spaced underlying cross bars, 16, one of which. is

adjacent to the front ends of said bars15.

Pivoted at 17 to the outer sides of bars 15 are extensible legs 18, each leg consisting of two members fitting slidi'ngly together and secured at any desired point of extensibility by clamping sleeves 19. To'brace the legsand side bars at different angles to eacliothenand also to act ae-a stop for the dumping element hereinafter described, the bars 15 are provided with plates 20 to which are pivotedbars 21, fitting against the inner sides of the legs and provided with longitudinal slots 22 engaged by clamping devices 23, j the said devices being for the purpose of securing the leg'sin a substantially vertical position irrespectiveof the,

inclination of the-bars 15, The bars 15 are provided at their inner sides with longitudinal stringers 24c equipped with suitably spaced anti-friction rolls 25 which project slightly above the said stringers and with the'latter constitute a pair of trackways.

Said stringers are recessed in their upper A, sides and'lower ends at 26,'t0 receive the free ends of a pair of bridge bars 27, pivoted at 28, in the recesses 12 of the stringers 10. To pivotally connectthe lower ends of bars 15 to the front endsof bars 3, the

rinses warps a1sh.,mbemat ma h end r t er ed an ravel s upon the hinged e bars. 27 so that the hooks, I shall be ra sed su'fliciently .to clear the crossbar ,2. L The bridgabars also serve Ito-r reduce tl'ie shock inci entto the e it vt bf iefit tea r t e dr e..,r epatins m m e as nce o sp ing. i. While renaming th upw r mo me t an w leihelding sa Catch t ppe the tre t 1 ofithel ragr .ceptacle enters the dumping member below the guard ra 1ls5 l and upon. 1ts roll-equlpped stringers 1 57, and; as the hooks 66 enter the loops 56, the major portionof the weight of the drag receptacle is upon the dumping member and the dumping action occurs, it being understood that justas the hooks are entering the loops 56, thecable 73 is placed under tension and ass result of the, continued forward movement of the scraper and hence of the cable 6 5), the pin ,74 is withdrawn and the clevis slips; outjof the snap hoolc- It will be seen that, due to the engagement of the hooks 66 with the loops 56, and ,the interpo-sition of the dragrecep- .tacle between the traclrways and the. guard rails oi the.dumpingmember, it will be impossible as thesdumpingaction occurs, for thedrag receptacle to either slide forward or tip forward out of the dumping member.

Assuming that the latch member of lever. 43

is either dispensed with or held inoperative,

for instance by the pivotedloop 75, carried by lever 43, it will be apparent that as the dumping action occurs, the lever 43 will swing in the direction indicated by the adja cent a row Fig. 3, and the spring 37 will be tensioned as shownin Figs. 1 and 2, because the downward movement of the. dumping member through the instrumentality oi arm 40, rocks the hinge rod and the other crank arms 36 and ll attached thereto. To restore the parts to operative position the operator swings the lever back to its original position and in so doing through the link 42 and crank arm 41 with the assistance of spring 37, reelevates the dumping member. As this occurs the weight of the drag receptacle will cause the same to slide downward from the dumping member over the elevating member and back to its original position on the base member. Should itbe desired to prevent the dumping action as the'loaded .drag receptacle enters the dumping member,

the operator can swing the loop 7 5 out of engagement with the handle of the latch mechanismandpermit the latch to engage the sectortti and thus lock the lever inrigid relation thereto.

It is obvious that with a machine of this characterpany loose material may be han died, and that such material can be expedi tlously loaded and elevated by means-of scrapers and dumped lIlbO wagons or carts or into a freight car orthe hold ofa vessel, or it maybe employed for filling trenches.

From the above description it will be apparent that I haveproduced a loading and unload ng apparatus embodying the features of advantage enumerated as desirable, and I wish it to be understood that I reserve the rlght to make all changesprcp- ,erly. falling within the spirit and scope of the'appended claims.
